Abstract

Provided is a connector structure of a stepless capacity control actuator of a reciprocating compressor including an ejector rod configured to transfer power provided by a driving structure to an unloader. The connector structure includes a housing sleeving the ejector rod, a connecting member including a flange part and a sleeve part, and a sealing assembly including a first end face sealing ring, a second end face sealing ring, a first seal ring and an oil leakage joint. A first side of the flange part is connected with a second end of the housing and a second side of the flange part is configured to connect with the driving structure. A second oil hole is formed in the sleeve part and in butt joint with a first oil hole. The oil leakage joint is connected to the first oil hole.
